Love the product idea.
This did much more than measure heart rate and sleep quality for me. I ve used it to manage my temper & emotions.
Controling your heart rate and keeping it below a certain level guarantees you never get mad essentially and forces you to pace yourself when discussing with other people.
WHY 4 STARS AND NOT 5?
Accuracy appears to be somewhat poor. Possibly because I picked the large ring which is rather big, but the small one would be too small for me and cut blood circulation.
In particular this is not very good at tracking fast heart rate (above 100-120) which occurs frequently during a workout and is important to track (eg i need to know if im at 120 or 160... but it seems it stays stuck in the low 100’s)
